Title: Verfahren und schaltungsanordnung zur erzeugung einer zündspannung für leuchtstofflampen
Inventor: KEGGENHOFF RALF
IPC: H05B41/298
Filed: 2001-03-16
Abstract: Der Erfindung, die ein Verfahren zur Erzeugung einer Zündspannung für eine Leuchtstofflampe betrifft, bei dem die Zündspannung mittels einer Wechselspannung erzeugt wird, die einem LC-Reihenschwingkreis aufgeprägt wird und eine entsprechende Schaltungsanordnung betrifft, liegt die Aufgabe zugrunde, die Sicherheit des Zündens zu erhöhen und eine Überschreitung maximal zulässiger Zündspannungen zu vermeiden. Gemäß der Erfindung wird dies dadurch gelöst, dass der Wechselspannungsgenerator in seiner Frequenz von einer Steuereinheit steuerbar ist und dass eine Messschaltung mit der Steuereinheit verbunden ist, wodurch die Wechselspannung schrittweise von einer hohen Frequenz zu einer geringeren Frequenz verringert werden kann, wobei die Lampenspannung zeitweise mit einem Sollwert verglichen wird und bei dem Erreichen eines Sollwertes der Startvorgang abgebrochen.

Patent WO-02100137-A1 (WO)
Inventor: DE STEUR HUBERT
IPC: B23K26/00
Filed: 2002-05-15
Abstract: The invention relates to a method in which both regions (3) of a printed circuit board (1), which are provided for rough conductor structures (31), as well as regions, which are provided for finer conductor structures (41) of the printed circuit board (1), are each structured by means of laser machining. To this end both regions (3, 4) are firstly coated with a continuous metallization layer and covered with an etch resist. The rough conductor structures are predefined using a laser beam (14) of a larger wavelength by exposing the unnecessary metal surfaces. In addition, the fine conductor structures are pre-formed by machining the etch resist with a laser beam (24) of a smaller wavelength. In a shared etching process, all exposed surface regions of the metal layer are subsequently etched away so that only the rough and fine conductor track structures covered by the remaining etch resist remain. The surfaces of the produced conductor tracks are exposed by removing the remaining etch resist.

Inventor: BECKER BURKHARD
IPC: H04B1/707
Filed: 2003-08-08
Abstract: The invention relates to a method for synchronizing a receiver and a transmitter which periodically transmits a sequence which is known in the receiver. According to the inventive method, a subset of possible synchronization times is determined in a first selection step by repeated correlation of the received signal with the known sequence and by comparison of the correlation responses calculated in the correlations with a threshold value. The threshold value is thus modified in an adaptive manner according to at least one parameter measured during said correlations.
Patent WO-2004051739-A1 (WO)
Inventor: FREYWALD KARLHEINZ
IPC: B81C1/00
Filed: 2003-12-05
Abstract: The invention relates to a method, which enables the production of an assembly comprising hermetically sealed, filled isolation trenches (1, 2), as required in the production of modern MEMS containing sensor components in hermetically sealed, cavities (8). Production is achieved by a slight enlargement (2, 3) of the isolation trench at specific points and by the use of a low-pressure deposition method for the trench isolation material. Sealing points laterally seal the hollow channels (5) that remain in trenches of a normal width in the longitudinal direction of the trench. The deposition method ensures the deposition of an approximately isotropic material and eliminates the risk of dangerously high gas residues in the cavities (8).

Title: Joining large pipes - by folded over edges
IPC: E04H12/28
Filed: 1970-07-09
Abstract: Very large diameter pipe is produced at least in part by the coiling of a strip, adjacent edges of which are joined by folding over, the rims being folded each time in the same direction. The folding connection is designed so that the sum of all folding angles of a given joint amounts to at least 540 degrees, and two folds are disposed at such distance from each other to permit the folding over of the free rim of the fold into its folding position. In the prefd. method a steel-aluminium bimetal strip coated at one side with a synthetic resin, is used. The process is employed for the assembly of storage silos and has the advantage of not interfering with surface coatings etc., on the strip used.
Patent DE-2050175-A1 (DE)
Title: Surface adhesive layer - applied on separately heated surface
IPC: B05D1/08
Filed: 1970-10-13
Abstract: When generating adhesive surface condition or applying adhesive intermediate layers onto surfaces for further coating applications by flame or hot spraying, heat is applied to the surface after or during the application of the adhesive material and the covering layer material is applied immediately afterwards or at least prior to the intermediate layer losing it's adhesive power. In the prefd. procedure the additional heat is applied by means of an independently controllable ring burner attached to the flame gun. The process is used for covering both metallic and non metallic materials and has the advantage of permitting the use of adhesives which are only active when heated, or are triggered off by heat.

Title: Valve operating gear for cut-off flap - using toggle leverage for secure closing
Inventor: KIRSCH HEINRICH
IPC: F16K31/50
Filed: 1973-10-29
Abstract: Cut-off flap design takes advantage of a toggle mechanism and avoids high bending loads on the threaded operating shaft at this point; also, by symmetrical design, permits the use of the same housing and parts for left-handed or right handed situations. The flap operating lever is shown in its closed position. The primary lever is at its lowest position. The primary lever is at its lowest position on the threaded operating shaft with a pin, in its outer end, at the bottom of the guide slot. The secondary lever is in a nearly straight line position relative to the first lever so benefiting from the mechanical advantage of the toggle effect. To open the flap, turning the operating shaft draws the nut, on which the first lever is hinged, upward.
